How to force LTE/GSM/CDMA auto (PRL) or any other Preferred Network Type.

Hello, I have no problem receiving an LTE signal on BCE (Canada) through the Phone Info Menu. I can select any of the preferred network types including LTE, LTE/GSM, CDMA, LTE/GSM/CDMA but it won't stay. Every day I have to go back into the menu and it reverts back to the first selection "WCDMA".
Does anyone know how to force this so it stays on LTE/GSM/CDMA. So it will stay on the LTE-enabled network unless there is a loss of signal and it reverts back to HSPA? It does this automatically when "LTE/GSM/CDMA is selected, but again reverts to CDMA within a day usually.
I did some searches here, but 99% of what comes up is just people asking how to enable LTE or if their network gets it?
Any ideas? Maybe some sort of macro thing.
Regards.

Add this line in build prob
telephony.lteOnGsmDevice=1
Save
Reboot
Now in settings/more/mobile networks u will have an option to choose and it will stick. U have to add the line every time u flash ROMs.
But I keep iron WC DMA/gsm for better battery speed is OK on h+

Thanks for the helpful reply man. I haven't edited a build.prop yet, so Ill have to check it out.

Alright thats all done now, works like a charm. Like that I have the option now either way. I typically stick to WCDMA/GSM when on the road or at work where LTE is spotty, but on days off for around town I would rather just be on LTE as I usually just looking up something quick when Im shopping or something.
Thanks again.

Nice
I keep it at LTE, it does have less bars but quality is same for me, speeds are amazing. Also 4G is only data, not voice, so when u have an active call it will change to 3G.(but that's not the phone it's the network)
don't forget to do it again if you flash new ROM, also Tethering WiFi won;t work, there is a fix but it's complected for me, so I just go to W/G if I need to share connection.

So, my Nexus 4 shipped today, and it'll be in my grubby little hands by tomorrow evening. I, unfortunately, can't activate it until March, as I have to wait for my Verizon contract to end, but I keep seeing this LTE stuff, with no real explanation. I do know that the Nexus 4 has an inactive LTE radio in it, but what's the use of activating it, if T-Mobile doesn't have LTE? Is this only for the AT&T users?

There are other threads dealing with who can access LTE in the USA. I am in Canada and on Bell.

I'm in Canada, using Fido. I activate the LTE on my Nexus 4. It works fine, but I'm not able to share internet with wifi hotspot.
I have Android 4.2.1 (latest OTA from Google).
There is a bug with this version or it's only because I activate LTE manually ?

As per the previous comment:

what is the fix to get hotspot internet sharing with the Nexus 4 ? Do i have to had a APn for 3G and swith that it to share my connection ?
I'm with the original firmware. Android 4.2.1

process com.android,phone hase stopped working
i recently got a rom from revolt on my n4 and i switched cdma to lte gsm wcdma auto
i also went into build.prop and wrote down telephony.lteOnGsmDevice=1. i went and to setting, more, mobile networks chose the correct setting. so now i got 4G. great i can make calls. GREAT. but i cannot receive calls...
need help with this. im really choked about this ROM

Even if I select "LTE/CDMA" in the Mobile network settings menu. The settings page keeps displaying "CDMA preferred".
Does this mean it didn't work? In quick settings, I see my mobile data connection as 3G Bell.
LTE only seems to work when using the *#*#4636*#*# trick in the Phone app.

Would you have by any chance the line for the built.prop to stick the setting to GSM Auto (PRL)?

Thanks, but LTE doesn't work in my country, its always stick on lte/gsm/wcdma but it doesnt detect my gsm so i have to manually set it on GSM only but wont stick here every time i restart my phone i have manually set it on GSM only otherwise it wont detect my network
Any advice ?

How can I make "WCDMA Only" the default selection?
Where I Iive there is no LTE and the coverage of the service is quite poor, so the phone keeps jumping between E and 3G/H. I have to manually go into the phone app and select "WCDMA Only" is there a build prop tweak to make the "WCDMA Only" the default option instead of "WCDMA Preferred"?
Thank you.

So is there a way to get the nexus 4 to work on Verizon ??

Aah Crap ! Well thanks man saved me from buying on guess i will have to stick with my rezound for now then

fixed it
For everyone still searching for a solution to this problem, this worked for me. Go to phone information and turn your radio off. Then switch to LTE/GSM/CDMA then power down, DO NOT TURN YOUR RADIO BACK ON. Now remove your Sim card, put it back in, reboot and you should be good to go. DO NOT HGO BACK INTO PHONE INFORMATION OR ELSE IT WILL NOT STAY
If it still isn't connecting try fiddling around with your APN settings.

[Q] s4 GT-I9505 missing DC-HSDPA/LTE

Hello guys,So im with three.uk they dont do LTE yet but they r about to roll it out very soon however they do DC-HSDPA and im in area where i should be getting it sadly im not getting it for some reason top of the screen shows only H+(mostly) sometimes H and 3G. If i go to connections->More Networks-> Mobile Networks -> Network mode i only get WCDMA/GSM(auto connect) or WCDMA only so this is what i get. I was reading that there is some problem with s4's shipped from korea and people advice to flash to unbranded stock well one was australian so i even flashed to australian firmware even to getman firmware so far no luck no lte in options not detecting DC-HSDPA just after flashing to getman/australian firmware i got an extra option in network mode and it is gsm only plus the other two i said before. So my question is how i could get this DC-HSDPA working and what indicator top of the screen will show instead of h+ will it show DC ? i was trying to find answers but no luck so far please help me outKind rengards Martin

Hi,
H+ will still display on your signal strength indicator, as DC-HSDPA is just a variant of the HSPA network system. to force the internet to always connect to a higher speed network set it to WCDMA Only.
There is no DC-HSDPA or HSDPA in the network selection, it is tied to the WCDMA system.

Root Explorer (or another), and go to data/property.
select persist.radio.lteon , edit it with a text editor and change the value from false to true.

4g / LTE Toggle / radio control

At work the 4g LTE signal for ATT is very poor in the building, but we have 4g repeaters for ATT to fix this issue. Unfortunately, phones are stubborn and like to stay on 4g LTE despite having 1 bar of signal vs full signal with 4g. I had this same issue on my iphone 5 but was able to easily force off LTE while i was at work and have a steady, reliable data connection. My Note 4 seems to have the same affinity to wanting to be on 1 bar of LTE, but I cannot figure out a way to toggle / force LTE off and just use 4g. Anyone have any ideas? Anyone know of an application I can use to resolve this issue?
Thanks

try settings...more networks...mobile networks....network mode....It should be in there..I have the sprint model so I don't know for sure...but that is where mine is....hope this helps

Unfortunately, there is no option for Network mode on the ATT version. I wonder if this has to do with voLTE....
I did find a backway to the network mode via *#*#4636#*#* but I am unsure of what I should be setting to "disable" lte while I'm in the building at work.

I think I've sorted this out now. If I change LTE/GSM AUTO to WCDMA preferred it seems to immediately switch and hold onto 4G. I do have to change it back. Maybe I will write something so I can quick toggle this since nothing on the app store seems to work.

hi,
If you are rooted ? You can use an xpose module called Intelli3G
I use it on my phone ,works 100% and switches smoothly/fast between eg 4G..3G automatic
eg if my data is of its on 3G as soon as i switch data on /wifi it changes to 4 G
For interest sake ,here is a link to market ,you can read desciption what it does ?

good luck

Try dialling *#*#4636#*#* and select the first entry (Telephone information). You can set your preferred network type there. On my phone there are a lot of options to choose from, including LTE only, WCDMA only, etc.

Switching betwen 2g/3g/4g

Hello
I'm with Leeco Le Pro 3 AI with stock rom 5.9.026s
I notice that my battery drops almost 25 % per 10 hours . Battery used when phone is idle - 30%. The reason for this as I think is that the signal in my place is not so stable so the phone constantly changes between 2g/3g and on some place in 4g.
When I go to settings / Dual Sim $ mobile networks / Network mode i see that it is on auto - ( 2g/3g/4g ( auto) ). The problem is that I can't set it expressly on 2g. There is no option on this settings to choose the type of signal.
If I click on Sim Card slot 1 ( I have only 1 sim card on my slots ) and next click on Netwrok Carrier there is 2 options - auto select and Search for Network. When i go for Search for network i found my local network signals and it shows 2g 3g 4g ... I choose 2g but this do nothing. The phone again is in auto mode ( 2g/3g/4g ( auto) )
So does anybody has any idea of how to expressly set the phone to use exact network carrier ( in my case 2g ) not to be auto?

I believe you can force certain bands by typing this into the LeEco dialer: *#*#4636#*#* and choosing "phone information". Select "GSM only". Use this with caution. Your SIM might stop working because your provider might not support 2G only.

I thought there was an option to choose 2g 3 or 4g separate ???

IDK. Just chose GSM only if you want 2G only. Or better yet, pop your SIM into the second SIM slot and you'll only get 2G. Much safer.

AFAIK, it's supposed to give you a bunch of options: https://www.learn2crack.com/2016/01/force-2g-3g-lte-only-mode-in-android.html
Otherwise just choose 2G or LTE as your preferred network type in Settings.
Maybe try an app like this: https://play.google.com/store/apps/details?id=www.extremedroid.com.a4gltetoolkit&hl=en

sk8223 - my settings doesn't allow me to choose between 2g /3g or LTE it is locked on auto! There is no option on my model to choose network type.
Sweeden - I thought so that there is such option just as your screenshot but for Leeco Le Ai there is no such one.
Also there is no option to switch off sim card when you are with only 1 sim card. Actually there is an option - but it doesn't work.
So I will try some kind of app to switch between network type
Leeco Le pro 3 AI has really awful ROM- good hardware but the ROM is the worst I ever used
I badly need a custom rom for this model

No I did not.. but as I see on this thread the link to the app it change the settings on the same place as the call combination *#*#4636#*#* ... So i suppose every app do the same things. But to use this code is not so bad ... from there you can choose, 4g it works!
The bad thing is that my issue with battery drain still exist so i will continue to investigate the problem. Phone in idle consume too much electricity - some **** app sucks my battery energy! Every day I have issue with this phone - it is so time consumption .. bug after bug

This works just for a moment for me! Any other tricks that can force 4G LTE even if there are no 4G LTE signal? Thanks
Edit:
Use this instead to force 4G LTE without the ROM changing it back to auto.

Select "Network Selecting" then change to LTE only. Don't mess with the others, I heard it might destroy your device.
